Operation Manual of INVT CHS100 AC Servo Drive 5 Running and operation
45
After switching on the power supply of the main circuit, do
not touch the motor line terminals even if the servo is not
started as this may cause electrical shock.
After switching on the power supply, do not touch the
electriferous parts as this may cause electric shock.
2) Checking after powering-on
After switching on both of the control circuit and main circuit power supplies, if the
power supply is OK, the Power indicator lamp on the front panel will illuminate in red
and the servo drive and servo motor will not generate abnormal noise. If there is no
fault alarm of the servo drive, the LED on the front panel displays the current speed of
the servo motor as default. You can set the default display parameter through
parameter PA.02. The 3-color indicator lamp on the front panel illuminates as blue. If
there is a fault of the servo drive, the LED displays current alarm sign and the 3-color
indicator lamp on the front panel illuminates as red. Please fix the fault by referring to
chapter 9.1.
5.1.3 Self-test before running of the servo
The self-test before running the servo is very essential, it includes the following items:
1) whether there are broken lines of the motor encoder
Rotate the motor shaft with hands at least one cycle to see if it reports an encoder
line break fault (Er-EC1 or Er-EC2).
2) whether there is abnormality of current detection
Verify whether the motor shaft is rotating while switching on the power, whether it
reports a current detection fault (Er-iTE) during power-on.
5.1.4 Parameter setting before running the servo
Parameter setting must be conducted before running the servo. You can set relevant
parameters via the front panel or communication to meet the function and performance
requirements of the site application. See chapter 6 for the detailed description of all
parameters of the servo drive. Some of these parameters need to be set according to
the site application demand. For examples, pulse input mode, electronic gear,
frequency division coefficient of encoder output, upper/lower limit of analog input, etc.
Some of these parameters need to be set according to the site debugging. For
